This inventionrelates tomachines for the automatic manufacture of' what: are known asFrench edge round paper boxes, and more particularly tothat type of automaticineans for assembling the rings and bottoni.. disks of the box in proper relative position and applying thereto av tape or Webv'vhich. is giimined on oneside tobe aiixed-to the circumference of the band or ring andrcover the projecting bead Where the rim extends beyondthe ring. One edge of. the laterally projecting tape is turned over and ironedto the bottom of the box and theother edge to be turned into the openV side ofthe box. and ironed-thereto. Particularly the presenty inf vention is an improvement. inthe type of. machine inventedby Burl H. Smith andas set forth in LettersPatent No;rl,006,885, patented October 24, 1911, to Whichreferencey is made for details of mechanism for the assembling of the rings :and` bottomsfor disks of the bottom in proper position, the present invention having for its objectto improve the mechanism for eeding,.cutting and ailixing the tape to the assembled,` box sections, andreference is had particularly to the above-named patent lfondetails relating to the box member assembling' mech? "anism in which no improvement is contemplated in the present application. is the bottom of the box is of greater diameter than the ring, when these are centered to receive the tape or web there is for-med an extension edge and therefore .the rim or'edge otV the bottom requires a greater'lengthrof tape than does the smaller ring perimeteni lt is therefore anY important object of this invention to provide for the stretching of. the tape While the box` isrotated and' the,

tape is aiiixed.. To that end -means are pro- V-idedto hold, the tape securely upto the moment ofapplication to thebox. n

. A further object of the present invention is to provide for the true alinement of.4 the tape,l after it has been guin1ned,.-With the ring and disk applied thereto in the form of a box section, to providefurther for the control, continuously through the operation of the machine, of the tape to be aflixed to the-box.V so that the tapesand sections' cuttherefromv are guided in true alinement to the box section to be covered, and it is a further object of the present invention' to provide improvements in the advancing mechanism and in the means for aftixing'the tape to the box and which incorporates'features designed to continuously and positively-hold'the strip in true alinein'ent' With thebox While it is being aiiixed thereto.

Jvt'fiirther object of the invention is to provide means for preventing the jamming of the strip oft'ape as it is advanced to the Patented: oet. 22, v19,118.-

aiiixing and box binding 1nechanism,.to prol vide means to take out slack of the tape duringitsapplication to the box, to prevent vvrinkling in the strip of tape; to so control the tape that it cannot be diagonally drawn and disalined" ivith' relation t'o the' box so that it Willbe affixed thereto in substantially true circumferential position, and further i is an object of the invention to provide for the nal crimping of` the tape at the Yoverlapping end thereof atl what is known as the horn Where the trailing end ofthe binding tape is laid upon the box." j

lVith these and other objects in View the invention consists in novel means for alin'- ing the continuous strip ofv tape with tho atlixing mechanism, and further consists in means for positively grippingl the tape at parallel positionsY on opposite sides of its surface andlongitudinally ott its length so as-to preventV disalinement during'the transter from-the guide to an atl'ixing device, and

Vfurther consists in novel" and improved means for aiixing the tape to the box, and

which comprises devices for positively'hold-v ing the strip up tothe vpoint of its act-ual application tothe box being'V bound, and

As before stated, the present invention relates particularly to improvements in means for feeding gumined tape to aflixing means, the latter operative to aliix the tape to a box section composed of a disk D, Fig. 2,

Vwhich may be fed from a magazine M particularly described. The assembled ring and disk are adapted to be circumferentially bound by a strip of" tape of suitable material and which may be composed of plural layers, as, for instance, a binding strip, a

color strip, and sometimes a finish or trim- Y ming strip, the tape being led from any suitable tape-forming or gumming mechanism, not here shown, but disclosed in U. S. Patents Nos. 1,218,417 and 1,218,418, and extending from this mechanism over a suitable tape guide 2, Fig. 3, thence rearwardly t0 a carrier wheel 3 which is moutned upon the upper end of a feed lever 4 connected at 5 to a link 6 extending beneath the frame of the machine and carrying a yoke arm adapted tc engage a respective cam mounted on a cam shaft 7. The operation of this mechanism is to intermittently draw a piece of the tape T forwardly as required and which is thence lead over the top of the roller 3 into a guide 10, Figs. 1 and 5., `the function offwhich is to properly aline and retain in alinement the tape as it moves toward the assembledsections of the box carried by the mandrel 125 when the latter is moved into position with relation to the downwardly lowered slide S carrying a bottom or disk of a box section.

The guide 10 is shown as formed in a portion of a suitable framework 11, illustrated in detail in Figs. 15, 16 and 17, and which latter is provided with a dove-tailedV chan- Y nel-Way 12 in which there is adapted to run icc 16 pivoted at 17 upon vthe main framework l for a suitable distance along the frame 11 and is provided Y with a vertical slot 11, Figs. 18 to 20, over which the tape is adapted to be advanced in iso l 28 having an upwardly extending arm which is provided at its upper end with aV horizon- 'tally extending portion, one end of'which,

29, extends toward the guide 10 while the opposite end extends away from the guide as at 30 and overhangs a rail 31 which is connected by suitable arms 32 to hubs 33, one of which is fixed to or forms a part of a sleeve 34 of suitable length having on its outer end 35, Fig. 5, an upwardly extending spindle 36 to receive a cam roller 37 which is adapted to engage a cam 38, Fig. l, mounted on a cam shaft 39. f

Arranged coplaiiar aboveV the jaw 25` in the slot 11 oit' the frame 11 there is a coperative jaw or blade 40, clearly shown in Figs. 4, 5 and 6, which extends longitudinally of the guide channel and Vis secured adjustably to a friarrying arm 41which has hub portions 42 which are loosely mounted upon the rock shaft 27 which carries the lower jaw 25, this carrying arm 41 extending rearwardly over andY parallel to the rocker a'rni 27 and has at its rear end a rearwardly extending lug or arm 42 which is adapted to rest upon a horizontally extending rail 43 which is connected by means of arms 44 to a rocker shaft 45 upon which the hubs 33 of the adjacent rail 3l are loosely mounted, this rocker shaft 45 being providedA at its outer end withan arm 46 carrying arcani roller 47 which is adapted to engage a'coinpleiiientary portion ofy the cani 38 whicli'also operates the cani roller 37 of the low yr jaw controlling rai] 31.

Preferably the coplanar jaws 25 and 40l are arranged with their adjacent edges adapted to grip on opposite sides of an interposed strip of `tape as it lies on the bottoni of the channel way inthe rame 11, the upper blade being provided with gripping teeth 40 to minimize the tendency of slipping of the tape and by preseiitingonly point contacts, avoiding sticking to the jaw edge. Preferably lthese jaws engage the tape with yielding pressure, and this is secured by means of suitable yieldingly actuated presser pins, one of whichV is shown at 42 pressedy downwardly by aspriiige2a which isinounted in a guide 50in the forni of -an upwardly extending tubular socket which is formed on or secured upon a plate 51 which is detachablysecured byV screws Y or other suitable means 52 to therear end of t-he carriage 13.

In a similar manner the lever arm 30 -of the rock shaft 27 which actuat'es the lower jawr25 ispressed down Vby. a'pin-30 which is actuated by ai spring in a socket 30a so that the upper jaw is yieldingly pressed upwardiwhen the rail 31 upon which the arm' 30' rests is lowered. To control the rrelative position of the jaws 25 `and 40 as they approach each other in the giiideway 10 of the frame 11, suitable adjusting means as screws 52 are provided in the top plate 51, these screws Ybeing adjustabletowi rd or from the adjacent"overhaiiging portions of the-,respective lever arms' 29 and 30V in 'im f obvious manner. v

In the operation of: the cooperative jaws 25 and 4U-these are adapted to be movedV rearwardly into the guideway 10, while lthey are in a respective open or separated position with the lower jaw 25vdrawii down below the bottoiii'ot the guideway 10 so as to freelyvpass beneath a strip of tape therein, while the upper jaw 40 is elevated a suitable dista-nce above the suriacerot the tape to clearit. After thejawsfhave been drawn lto l their rearward limitotinovement-iii the guidewayl() they are permitted tov iclose V Y mounted is adapted to be propelled for-V Vwardly by the actuation ot the lever 16 'upon the interposed pieceoftape and then the carriagev 13 upon which thesejaws are interposed-pieceof tape, and vthe latter isV Vdrawn into the rear end ofv the guideway over the roller 3 while the leading end ,of

the tape is-traiisferred from the guideway in a direction alined with the longitudinal axis of the guideway and is adapted to be placed upon a suitable. aifixing mechanism. Y

which is mounted `for "reciprocation toward and from the fixed guideway to approach the forwardly advancing carriage 13, and" when the blades forming a vise on the carkriage are properly positioned with respectV to the rearwardly moved atiixing device,` means are provided for clamping one edge ot the tape as it is held above the receiving plane on the aiiixing device so'that then the tape may be advanced by the 'movement of the aiiixingineclianism to the point ofappli'- cation of the tape on a box to be bound in the machine.

This aitixingniechanism is lclearly illustrated in detail in Figs. 7, 84 and 9, aiidcom-` prises a slide which maybe ot suitable construction and is arranged for reciproca'-v tion 1n proper alinement' in a guid'ewajv 56 forming a portion. of the frame 11, the lcwer'suriace of the with a rack 57,' Figs-7 land 3,; adapted to engage a pinion A59 mounted on a shaft 60 which is mounted in suitable bearings on the frame, this shaft'extendingl transversely7 of the machine with relation to the line of feed ofthe tape, as shown inFig. 2, andis:

slide being providedprovided with a pinion 61 adapted to inesh with a gear 62 which is secured on a gear shaft (53 having a pinion 64I, Fig. 8, which is engaged by a-rack` 65 on the shank of a connecting rod or yoke 66 straddliiig the cam shaft 7, and which is adapted to be actuated through a cani 68 on shaft 67 so that the carriage 66 may be positively shifted rearwardly in proper time.

Projecting upwardly from the slide 55 there is shown a set of standards 69 and an end bearing or upright 70, the standards 69 Y bein' adapted to receive a ivot rod 71 u Jon which there is mounted a plurality of oscillating arms 72, `these projecting downwardly from the pivot rod 71 and having cam rollers 78 onv their lower ends while the upper ends of the arms 72 are provided with overhanging or clamp lingers 7 l which are provided with operative gripping surfaces at their tips adapted to bea-r a section of the tape down upon a plate 75 which is secured to the top of the end standards of the slide 55. The top of the plate is designed to forni a longitudinal plane substantially flush with the bottom of the eliaiinel or guideway 10 from which the tape is drawn by the reciprocating vise jaws 25 and 40, and arranged parallel to the plate 75 there is connected to the standard 70 an overhanging and longitudinally disposed plate 76, one edge of which is spaced in juxtaposition to the adjacent edge of the plate 75 so as to form a narrow longitudinal recess 77, Fig. 7, for the reception of the edge of the bottom of the boXas indicated inV dotted lines in this figure, while the ring of the box is adapted to rest circumferentially upon the top or plane surface of the plate 75 which is overliung by the fingers 74 of the aliiXer clamps. For the purpose of controlling the 'opening and closing action of the clamp fingers 72 these latter are adapted to be pressed downwardly at their lower portions automatically by means of respective springs 78 arranged in suitable socketstherefor provided in the upper portion of the slide these springs 78 tending to rock the lower ends of the lingers 72 outwardly and bear the overhanging gripping portions downwardly upon the top surface or plane of the plate 7 5 when the vise plates have carried a strip of tape into superposed position above the plates 75 and 7 6 of the sliding aiixer when. the latter has been moved backwardly through means of its actuating mechanism to a position adjacent theiiXed guide 10 on the frame 11 at which time the structure, forming the carriage` and the vise blades, has been advanced so that Y the front end of the carriagev or vise structure abuts the rear` end of the affiner asl shown in Fig. 18, thus insuring for the positive emplacement of a strip of. tape as it is advanced by the vise jaws over the ailixerv at which time the clamp fingers 72 may be released to secure one edge of the paper on the plate 75 while the vise jaw 40 is maintained at rest by its cam slightly above the plane of the aliiXer and the lower Yjaw is loweredV so. as to prevent the gripped edge of the paper between the vise jaws from being depressed into the longitudinal groove or channel 77, and thereby effectually preventing tlie upwardly curling or bending action of the strip of tape as it isarranged over the aiiixer. 1 The springs 78 are preferably of greater strength successively along the afliXer so that the last one to release is the strongest of the series as it is the only one effective when the preceding lingers have been lifted. When the carriage has been moved to the position shown in Fig. 20 through the action of the cam 21 indicated in Fig. 2, the forwardly advanced end of the tape carried by the vise blades or aws is adapted to be severed by suitable cutting means so that the leading'l end of the severed section of the tape may then be passed to a position over the aftiXer to be clamped thereon. The tape is then clamped down and the vise and aliixer given a synchronous forward movement by cam 68. Various forms of cutting mechanism ma) be utilized, and, in the present instance, is illustrated in Figs. 12 and 13 as comprising an upper cutting blade 80 afIiXed to a blade head 81 on the end of an arm 82 which is secured on a rocker shaft 83 mounted for oscillation in ajournal 8l which is attached to or formed upon one side of the frame 11, the rocker shaft 83 extending through the journal 8st and carrying a pinion 85, and also carrying at its outer end a lever arm 86y provided with a cam roller 87 adapted t0 engage a cam 88, Fig. 1, the function of which is to oscillate the lever arm 86 in proper time so as to swing the knife blade 80 downwardly into coperation with a blade 90 which is secured upon the outer end of a lever arm 91 having a hub portion 92 pivotally mounted upon a fixed stud 98 below the journal 84 ofthe upper rocker arm. The concurrent motion of the lever arms 82 and 9i of the cutting mechanism is secured through the meshing of the pinion on rock shaft 88 with a pinion 85 secured onY the hub 92 of the lower blade 91. Afterthe strip has been vcut throughthe action of the cutters`80 and 90, the vise jaws or blades with their carriage are advanced progressively and synchronously with the afliXer slide 55 and the latter caused to carry a clamped tape forwardly into position beneath the boX being bound. For the purpose of preventing the leading or pick up end of the tape from sticking or jamming with the adjacent surface of the aflixer plates 7 5 and 7 6 as the tape is carried over the atxer by the vise, and to permit the tape to iis be free from tensional strain until the initial short length has been firmly aiiixed to the box, this leading end of the tape is preferably supported in an elevated position on the 11p-lifted lower jaw through means of an auxiliary gripping device or what will be hereinafter termed as a smoother which is clearly illustrated inFig. 4 as comprising a nawl 95 which is pivoted at 96 on the upper and forward end of the upper blade 40 of the vise and is pressed yielding/ly downward by a spring 97 so that the interposed leading end of the tape is held against the foremost end of the lower blade or jaw 25 while this latter passes into the slot 77 between the plates 75 and 76 on the top of the afiixer. When the vise blades have been moved to their foremost position with respect to the aifixing position of the tape where the box is being turned through means of the mandrel 125 for the purpose of preventing the pick up end of the tape from being pressed down on the plates 75-76 of the afiixer rather than to the box as the lower jaw of the vise 25 is lowered through the action of thc cam mechanism, there is provided on the top surface of the affiXer plate 76 a cam plate 76', Fig. 11, which is adapted to engage with a roller indicated in dotted lines at 95 so that vthe smoother 95 issupported in an elevated position above the top plane of the plates 7 5-76 until the leading end of the tape is securely affixed to the rotating box ring, and then as the affixer slide 55 moves forwardly the cam plate 7 6 is withdrawn from under the roller 95 of the smoother' and the latter is then allowed to press down upon the tape and smooth this out upon the plates 75 and 76 of the advancing aiiixer members to smooth out wrinkles and place the tape under tension as it is drawn by the rotating box upwardly from the surface of the aifixing plates 75 and 76.

In the operation of the aiiixing device as the slide 55 is moved. rearwardly to the cutting position of the mechanism and in a p0- siticn to receive a portion of the tape as it isadvanced by the vise blades, it is necessary to lift the gripping ends 74 of the clamp fingers 72 of the affixer so as to permit the arrangement of the tape in superposed position'above the plates 75-76 of the afiixing device, and to that end the ngers 72 must be mechanically swung inwardly at their lower ends against the action of their springs 7 S to cause the opening of the clampingV ends 7st and this opening movement is secured through the medium of a cam rail 100, Figs. 7, 8 and 9, which is shown assecured upon the lower ends of a pair of arms 101 which are secured at their upper ends to a rock shaft 102 mounted in suitable bearings 103 on the frame 11, the rock shaft being provided with a laterally extending lever arm 104 carrying a cam roller 105 at its outer end adapted to engage a cam 106 which in the present instance is shown in Fig. 1 as being formed in the cam wheel which carries the cam 88 Vfor actuating the cutters, although obviously this cam 106 may be arranged in any other suitable manner and position. l/Vhen the aflixer moves rearwardly the cam 106 throws the cam rail 100 inwardly at the lower ends of the clamp fingers 72, and as these fingers are carried rearwardly the cam rolls 100 located thereon ride onto the vinwardly swungv cam rail 100 and the clampingends 7 4 of the fingers are lifted to a position in vwhich they are all open at .the same time. Then when the tapeV has been positioned above the plates 7 5-76 by the advancedvise the cam 106 operates to withdraw the cam Vrail 100 so that the springs 78 automatically swing the linger gripping portions 74 downwardly upon the interposed and adjacent side of the strip of tape, and this is thereby clamped to the plate 75 and its alinement positively secured and relative slipping and wrinkling is elimi-l nated. Obviously as the affixer device moves forwardly ktoward `the afHXing position at which the tape isapplied to the rotating box it is necessary to successively lift the gripping ends 74 of the fingers so that the tape may be clear itself from the top plates 7 5-76 of the aifixing device as it is taken up by the rotating box, and this successive release of the gripping finger ends 74 is secured through means of a fixed cam 110, Figs. S and 9, disposed in the path of the rolls 100 as they are carried `forwardly with the moving afIiXer, the operative end of the cam 110 reacting against the-first finger as' the latter engages the cam so that the clamping portion 7 -i is released as the tape is taken up by the boxI` and then in successive order the following fingers are tiltedto release the tape until the whole length has been disengaged from the aifixer plates and wound onto the rotating box. Fastened by screws or other means 11% on the end of the rait 100 is a bridge plate 111 onto which the fingers pass as the clamps are moved back rearwardly from the adjacent cam 110 on to the cam rail 100.

From the foregoing it will be lseen that clamps on the -aflixing device, allof which operate to control the alinement of the tape from the time it is led into the guide 10 until it is finally applied to the boX section being wound.

In addition to these means for controlling the alinement of the tape continuously during its passage through the machine to the box it is also desirable to prevent accidental shifting longitudinally of the tape, and to provide means for taking up the slack which may occur for any reason in the length of the tape, and these purposes are accom plished through means of suitable gripping devices which are shown in Figs. 4 and 5 as involving a presser finger 115 which is mounted upon a rocker shaft 116 supported in an upright bearing 117 at one end of the guide 10 and on the side of the frame 11, this finger having the function of bearing down upon the introduced tape in the guide to prevent its rearward movement when the guide wheel 3 is swung rearwardly during a take-up mo vement of the lever 4. But for the purpose of preventing the unnecessary friction of the finger 115 on the tape in the guide 10 when the vice is advancing to transfer the tape from the guide to the afxing mechanism, it is preferable to lift the linger at such time, this being accomplished through means of a. cam lever 121 which is pivoted at 120 on the side of the frame 11 and which at its rear end engages a lever 122 fixed on the end of the rocker shaft 116 of the finger 115 so that the finger is lifted against the tension of its actuating spring 123, one end of which is connected to an arm 124 and the opposite end of which is connected to any suitable fixed point as a pin 123. The lever 121 is provided with a downwardly extending 'arm 126 bearing a roller 127 which is shown in Fig. 1 as engaging a complementary cam portion on the cam wheel 88.

For longitudinal tensioning of the strip of tape as it advances through and rests in thea guide 10, there is also provided a tensioning device in the form of a pawl 130, Figs. 4 and 5, which is mounted upon a rocker shaft 131, the latter being connected to a tensioned spring 132 the opposite end of which is secured to the pin 1231 for convenience. sioned pawl 130 is adapted to press the interposed strip of tape downwardly into a recess 133 formed in the bottom of the guide, the strength of the spring 132 being such that` it will bear the finger or pawl 130 lightly onto the upper surface of the interposed tape and thus longitudinally tension the latter to take up any slight slack that may exist and thus prevent transverse wrinkling of the tape. In addition to the foregoing the pawl 130 by depressing the tape in the recess 133, also acts to pull the tape rearwardly from the upper knife to The swinging end of the ten.

which it sometimes sticks and as the knife moves up it might carry this end of the tape with it and disaline it, as the tape is held in the rear of guide 10 by finger 115 against a' forward pull it is obvious that the front end will pull back as the tape is depressed inv the recess. To prevent the forward end of the tape from curling up and being caught by the rearwardly moving jaws, there is provided adjacent the forward eiid of the guide 10 another pawl 140 to press down upon the forward end of the tape and hold it from being drawn intoV the guideway or guide 10 through the action of the tensioning finger 130. In operation after the aiiiXer has been moved rearwardly into proper position to cooperate with the vise to receive the leading portion of the tape from the guide 10 and to be in proper position to hold the tape while it is being cut through the action of the cutters 80 and 90, it is then desirable that the afiixer be led forwardly, and while this forward movement is taking place the mandrel 125, which is adapted to turn or rotate the box, is preferably rotated at a speed slightly greater than the linear rate of advance of the aiiiXer so that the tape is taken up and given a slight tension as it is lifted from the afiiXer surface, this being for the purpose of avoiding any creasing of the paper as it is laid on the boX and to prevent transverse wrinkling, and to that end the mandrel 125 is adapted to be rotated in proper time withV relation to the movement of the affixer, and such timing is secured in the present instance through means of a gear mechanism which is clearly illustrated in Figs. 1 and 2 in which there is provided on the shaft 60 a pinion 150 which is adapted to mesh with a rack 151 formed on the lower portion of a slide 162 which carries on its upper portion a rack 163, this being adapted to mesh with a pinion 164 for rotating the mandrel 125, The rotation of the mandrel is secured when the latter is shifted from the position shown in Fig. 2 to a position beneath the slide S in which the parts are assembled, the longitudinal shifting of the mandrel being secured through any suitable cam mechanism as is illustrated at 125', Fig. 1. I/Vhen the mandrel has been shifted to the position to assemble the parts the gear 164 is interineshed with the rack 163 and then the gear is released from the control of a suitable locking mechanism, including a bar 165, which engages an adjacent cam 165 to hold this against rotation when it is in the retracted position as in Fig. 2 where the ring is discharged from the mechanism. The

locking bar 165 is shown as connected to ak rocker arm 166 which is pivoted at 167 on a bearing 168, the rocker arm having a rearwardly eXtending'lever 169 provided with a roller 170 operating on al cani., 1-71 on c am shaft 39, and by which `cani lthe locking 4bar llis adapted to be -thrown out of locking'relation to the cam 165when thefpinion 'has been intermeshed with therack 1.63, and

thereby permit the rotation of vthe mandrel atvthe proper speed and time'asl the aflixing device moves forwardly. i

During the operation of aiiixing the tape to the box section the French edge, as it is termed, of the cap or top of the box, rotates in thegroove 77 of the aftixer, and for the purpose of giving a final smooth finish to the trailingend of the tape as it is woundy upon the box to finish what is known as the l lhorn at the latter endV of theV tape,there Ythe slot 77, las shown in'FigfS. Thisis obtained by fastening to the plate for rin'-v stance, a crimper 75', theinner edge of which is so disposed with relation tothe adjacent edge of the opposite plate as to "subject the French v'edge of the box on bothV sides at the zone of thefllet of thelapping end or horn of the box to slight additional pressure so that itr is snugly lapped down onto the underlying surface of the tape onv the box.v Any'desiredV pressure may be givenY forv this' purpose by adjusting the plate 76 against the bottom ofthe box. This is done "by means ofthe two adjusting iscrews 76", Figs. V8' and 9 by screwing' one in andthe other out and then locking theml with the center and' top screws 76C. This plate 7G also serves to turn the projectingr-v paper about the bottom. Means for turning' in the other projecting edge of paper into the box and flattening down the paper on both ends of the box are shown in the Patent No. l,0Q6,885.

'Preferably/i, the plate planes which are slightly aboveV the general longitudinal plane of the plate so Vthat the tapewhen being picked `up;7 by the rotating box, receives pressure between the'elevated surfaces so as to insi'irethelirm Vapplication of the leading end -to the trailing end 'of the sectlonof tape to the box. -Thisinitial pressure however, is preferably relieved after' the starting vend of the tape has been applied to the box ring so that the peripheral over travel abovementioned is permitted to draw or stretch the top tightlyTv onto'- the box without pressure from the surface of theplate between Vits ends and thereby avoiding straining, cracking or breaking it as would be the case if the Vpressure was continuously 25 liasiat its ends applied along the surface of the plate as the. tape wa-srrolled on to the box.
